Forget the K & N Air Charger! It is a waste of money. I bought one. Cost like, $240. Installed it. My ET times actually dropped, not to mention the noise level increase from the engine compartment, unless you actually like more noise. I took the dang thing off. I'll sell it to you for $150. New, used once.

Save your money and buy a tuner kit for 1 or 200 more.

Personally, I bought a wet/dry nitrous kit and installed it dry because I didn't want to fool with the fuel system. Easy install. Press the button, and I'm gone.

Stay true!

Eugene, how long did you use your CAI? I want to get one and am interested in buying yours.

Hi ChevImpalaBoy4. I ended up putting the K&N back on to see if it would help with gas mileage. While it did give me a little (Maybe 1mpg), I've got to tell you.

With no other mods, more air, changed the power curve of the engine. The low RPM torque has dropped off noticably. Frustratingly so. While the top RPM torque has increased a little, it is not worth the price of the K&N.

This issue is very pronounced due to the long final gear ration the 2006 Impala has. The gears are veeeeeerrrrrrry tall. Erego, the car spends most of it's time, even if you are racing someone, in the low to mid range RPMs. If the final gear ratio was not so tall, and I know because I may have had the car up to 150+ mph with little sweat, this would not be an issue. But, because it is so, when you crank first gear up and finally feel the little extra power kick in at 5-5.5 grand, you shift into second at redline and the RPMs really drop back into the low mid range. Second gear, then, is REALLY tall and while you are waiting for your engine to rev back up to the power zone, the other guy is calling you a clown and pulling away.

Save your cashola and purchase a Predator tuner and dry shot nitrous. Of course, if you do this, you better plan on a shift kit or changing transmissions, as the stock unit is a total piece of crap. Ask the thousands of people, me included, that had to replace theirs, and I don't even run the car hard!! The wife won't let me.

Do the NOS

I put a wet/dry NOS kit on my Impala two years ago. Installed it as a dry setup as I didn't want to mess with the stock fuel delivery system. Also installed a water/methanol injection. The NOS jets are tuned for a mild hp increase. When the NOS and Methanol are kicked on though, it makes you smile.

Rarely use it though since I had to replace the tranny $$$$. I envision parts spraying out from under the car if I hit the button.:bang:

I'm used to old school cars like my 65' GTO or 80' Malibu Coupe. :beer: Parts are plenty and inexpensive, and easy to modify. New heads? No sweat. New cam? No problem. Higher compression pistons? Lots of work, but no EPA issues. NOS? Set it to max with confidence your drive train won't turn into scrap parts.k3:

The new computer controlled, EPA regulated, must pass government enforced state inspection ponsey scheme cars are a pain in the rear. Performance parts cost through the nose.

It's the governments way of trying to get all of the po' boy home built hot rods off the street. Why, you can't have a car that is faster and more agile than the police slug Crown Vics, don't you know that?:yikes: 'You vill sit down and you vill shut en zee up!' Sell that muscle car! Buy an electric hybrid! I don't think so.

LOL!
